Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

  1. Natural fire scenario

    Fire design by means of a parametric temperature-time curve according to DIN EN 1991-1-2

    With RF-/STEEL EC3, nominal temperature-time curves can be used in RFEM or RSTAB. The standard time-temperature curve (ETK), the external fire curve and the hydrocarbon fire curve are implemented. Moreover, the program provides the option to directly specify the final temperature of steel.

  2. Insert in RF-/TOWER attachments

    Creation of a user-defined antenna support for RF-/TOWER attachments

    In the following, the creation of a user-defined antenna support for use in RF-/MAST extensions is described in detail.

  3. System, Loading, Internal Forces

    Cross-Section Design of a Column Under Axial Force and Bending

    In this technical article, a hinged column with a centrally acting axial force and a linear load that acts on the major axis is designed according to EN 1993-1-1 with the aid of the RF-/STEEL EC3 add-on module. Column head and column base are assumed as a lateral and torsional restraint. The column is not held against rotation between the supports. The cross-section of the column is an HEB 360 from S235.

  4. Maximum vertical deformation Crane runway beam with rigid supports

    Method for determining the allowable deformation of crane girders

    This article describes the different options for determining the allowable deformation of crane girders. Since multi-span beams and flexible lateral supports (curling bracing) are used in practice, clarity is to be created here about the selection of the correct method.

  5. System Sketch

    Designing Welded Connection of I-Section

    A welded connection of a HEA cross-section under biaxial bending with axial force will be designed. The design of welds for the given internal forces according to the simplified method (DIN EN 1993-1-8, clause 4.5.3.3) by means of SHAPE-THIN will be performed.

  6. User-Defined Parametrized Platform

    Creating a User-Defined Platform for Use in RF-/TOWER Equipment

    The following technical article describes the creation of a user-defined platform for use on a four-sided tower in the RF-/TOWER add-on modules. First, start with an empty model of the type 3D and define four nodes. The numbering and position of these nodes are very important here.

  7. Model, Dimensions, and Loading

    Comparing the Stability Analysis of a Column Containing Internal Forces from Load Combinations with an Enveloping Result Combination

    This example will show what you should consider when you perform column design for bending and compression with regard to the internal forces from load combinations and result combinations.

  8. Window 1.5 Effective Lengths - Members

    Fire Resistance Design According to DIN EN 1993-1-2

    The fire resistance design can be performed according to EN 1993-1-2 in RF-/STEEL EC3. The design is carried out according to the simplified calculation method for the ultimate limit state. Claddings with different physical properties can be selected as fire protection measures. You can select the standard temperature-time curve, the external fire curve, and the hydrocarbon curve to determine the gas temperature.

  9. Stresses and Classification

    Classification and Ultimate Limit State Design of SHAPE-THIN Cross-Sections

    When designing a steel cross-section according to Eurocode 3, it is important to assign the cross-section to one of the four cross-section classes. Classes 1 and 2 allow for a plastic design, classes 3 and 4 are only for elastic design. In addition to the resistance of the cross-section, the structural component's sufficient stability has to be analyzed.

  10. Cantilever with Lateral Support

    Influence of the Parameters for Lateral-Torsional Buckling on the Design in RF-/STEEL EC3

    The input windows in RF-/STEEL EC3 distinguish between the flexural and lateral-torsional buckling analysis. In the following, an example will show the parameters for lateral-torsional buckling.
